Yokasta Valle and Thi Thu Nhi Nguyen both easily made weight for their historic clash.
The pair of strawweight titlists each weighed 104 pounds for their IBF/WBO title bout, marking the first ever unification fight to take place on Costa Rican soil. The scheduled ten-round bout headlines a Golden Boy DAZN Fight Night show Thursday evening Ciudad Deportiva Heiner Ugalde in Valle’s hometown of San Jose, Costa Rica.
Valle (25-2, 9KOs) attempts the sixth defense of the IBF title she claimed on the road in an August 2019 split decision win over Joana Pastrana in Marbella, Spain. The 30-year-old from San Jose fought in her home region for her next six fights before making her U.S. debut in a ten-round win over Lorraine Villalobos in her most recent bout on June 11 in Anaheim, California.
The win over Villalobos was added to a DAZN show presented by Golden Boy Promotions, who officially inked Valle to a co-promotional deal that was announced two days later. Valle is also promoted by MarvNation Promotions.
Nguyen (5-0, 1KO) will attempt the first defense of the WBO title. The 25-year-old from Ho Chi Minh City, Vietnam hit the road to claim the belt in a ten-round, unanimous decision over Etsuko Tada last October in Ansan, South Korea. Thursday’s fight marks Nguyen’s first outside of Asia and third in a row away from her home country.
